The G3 comes standard with one 10/100Base-T(X) Ethernet, two RS-232 and one RS-422/485 serial ports and support serial to Ethernet conversion. Additional Ethernet, RS-422/485 and USB Host ports are also available on specific models. A maximum of up to five high-speed serial ports are available. CANopen, serial ports, DeviceNet, and Profibus communication cards can be installed after purchase to further expand the G3’s connectivity.

Communicating with over 300 different protocols, G3 HMIs are among the most powerful HMI communication platforms available today. They can manage vendor-specific applications and provide the ability to network-enable existing equipment. Select the PLCs, drives, motion controllers or PID controllers that work best with your application, and control them all from one Red Lion G3 HMI.

With its built-in data logger, G3 HMIs offer a powerful means for recording continuous data as well as events and alarms. Data can be acquired from any or all connected devices and compiled into CSV-formatted files, where it can be stored, displayed, emailed or automatically synchronized with a server.


The Red Lion G3 HMI operator panels are far more than ordinary HMIs, offering functionality above and beyond the industry standard. The G3s are field proven with a remarkable track record of durability in harsh environments.

Red Lion’s G3 HMIs feature a keypad and/or resistive analog touchscreen and is available in display dimensions of 3.2 inch to 15 inch. Most models are available in color, while the smaller units are available in monochrome. The 3.2 inch, 5.7 inch and 10 inch models are available in outdoor versions which include a UV rated finish and sunlight visible displays. Keypads are standard on all models, and range from 8 to 32 buttons.


Remote Monitoring and Control:
The G3 HMI line excels at keeping personnel informed of machine and process performance. With its built-in web server, remote personnel can monitor as well as control equipment from virtually any networked device. G3 series HMIs can also alert personnel about existing or pending issues via email or SMS text messages to ensure problems are addressed quickly in order to minimize downtime.

Crimson Software:
Red Lion’s powerful Crimson® 3.0 software is a remarkable programming platform that unlocks the unique power of the G3 with just simple drag-and-drop, point-and-click configuration. Unlike competitive HMIs that charge extra for cumbersome software, Red Lion’s Crimson software is readily available for download.
